Do you mean then that you scroll the window up and down by one line,
but the cursor stays the on the same line?  If so, I have something
similar (I'd be interested to see yours), and I bind them to
<kp-subtract> and <kp-add>.  I know they're not necessarily next to
the cursor keys as you asked for, but they are quite easy to find for
me, as they are on the corner of the keyboard.

Obviously, I don't do a lot of number crunching, as those keys are now
useless unless overridden (as they are in calculator-mode).

In case anyone's interested, here's my version:

(defun scroll-in-place (scroll-up)
  "Scroll window up (or down) without moving point (if possible).

SCROLL-Up is non-nil to scroll up one line, nil to scroll down."
  (interactive)
  (let ((pos (point))
                (col (current-column))
                (up-or-down (if scroll-up 1 -1)))
        (scroll-up up-or-down)
        (if (pos-visible-in-window-p pos)
                (goto-char pos)
          (if (or (eq last-command 'next-line)
                          (eq last-command 'previous-line))
                  (move-to-column temporary-goal-column)
                (move-to-column col)
                (setq temporary-goal-column col))
          (setq this-command 'next-line))))
